Starting from the relation between structure and properties of polymer, high molecular polysiloxanes containing of different content of aminopropyl groups were designed and synthesized.
从聚合物结构与性能关系入手，设计合成了高分子量的不同氨丙基含量的含氨丙基聚硅氧烷。

The linear polysiloxanes can be used to copolymerize with other polymers to improve the flame retardancy, and the branched have better thermal stability, compatibility and flame retardancy.
The results showed that the average molecular weight of methyl hydrogen silicone, amine structure and Si content in amino modified polyether polysiloxanes have some effects on APEPS performance.
